Abstract: Creep property of undisturbed and reconstituted Japanese clay was presented based on drained triaxial compression tests. Creep tests were performed several times during monotonic primary loading, unloading and reloading. Test results show that: (1) the amount of creep deformation during monotonic primary loading depends on strain rate before creep, creep stress level, and creep time; (2) during monotonic primary loading, the stiffness increasing magnificently shortly after creep; (3) the direction of creep will change from positive creep; to neutral creep and negative creep during unloading, while during reloading, it will change from negative, to neutral and positive creep.

Key words: creep, viscoplasticity, soil mechanics
